500 Internal Server Error on VPS Panel

Hi!

We are experiencing 500 Internal Server Error problems while trying to connect to the control panel of one of our VPS (ubuntu-8.04-x86_64).


Here are some logs:


root:/# cat /var/log/sw-cp-server/error_log
2010-10-24 19:22:31: (log.c.135) server stopped
2010-10-24 19:23:37: (log.c.75) server started
2010-10-24 19:25:45: (log.c.135) server stopped
2010-10-24 19:26:09: (log.c.75) server started
2010-10-25 12:34:35: (log.c.135) server stopped
2010-10-25 12:43:24: (log.c.75) server started
2010-10-25 13:09:10: (log.c.135) server stopped
2010-10-25 13:09:10: (log.c.75) server started

It's not a disk space problem:

Any ideas?

Thank you so much for your time.
 
Maybe it is related to lack of resources for this VPS? Did you checked failcounters with

# cat /proc/user_beancounters

Did you checked Virtuozzo logs for possible OOM killers for this VPS?
 
Hello,

I have seen that error due to a corrupted/missing table in the psa database. Ask your Web Hosting provider to disable "Offline Management" and the exact errors will appear in browser.


Cheers.
